Built as a DH.34, later modified to DH.34B standard.
Arguably both variants were a tad underpowered with a 450 hp Napier Lion (compared with, say, the DHC Beaver or MH Broussard with the PW Wasp Junior developing the same power).
Note, just visible in the second photo, the triangular passenger door on the starboard side, shaped that way to allow a spare engine to be loaded into the cabin when necessary.
Note also the pilot's access ladder, which flew attached to the aircraft!
